这几天的问题依旧没解决，我是否不太适合做这一行了。我是一名普通学校的实习生，这个其实是我的第一个项目任务，完成一个上位机开发。我现在把我写的Visual studio代码放在这了。如果今天还是没完成，我在考虑是否要辞职了。可惜了我这三周的工作时长了，但是我真的受不了天天对着完成不了的任务了。
望有人个给我个方向，或者帮我看看有没有解决的方法。 一名物联网工程专业人未毕业但是想从事嵌入式的学生
这是我的数据显示函数
private void analysisdata()//数据接收分析
{
//if ((Readbuff[0] == 0x55) && (Readbuff[19] == 0xAA))
//{
//int checksum = 0;
//for (int m = 1; m < 18; m++)
//{
// checksum += Readbuff[m];
//}
//byte check = (byte)checksum;
//if ((check == Readbuff[18]) && ((Readbuff[3] & 0X08) == 0X08))
{
int rev;
int stack;
int softstart;
textBox1.Text = Readbuff[1].ToString();

这个是我的读取数据按钮

这个是我的串口接收函数
